"My father was Martin Hamilton," he said. "He cleaned floors at Johns Hopkins in Baltimore for thirty years. Night shift, most of it. He came home smelling like disinfectant, and he always had something to read stuffed in his coat."
Miles looked up from his soup. "Medical journals?"
Hamilton nodded. "The same kind you're carrying. Doctors threw them away when new issues arrived, and he asked whether he could take the old copies home. He'd read them until the sun came up, then sleep four hours and go back to work."
Martin Hamilton had been a tall, quiet man with a talent for making difficult things understandable. He could repair a leaking sink, calculate household bills without a calculator, and explain the difference between a virus and a bacterium after reading about them in a discarded journal. Gregory had once watched him describe the heart's chambers with such care that the kitchen table seemed to become a classroom. As a boy, Gregory had assumed his father knew almost everything.
But Martin had never been given a path into a profession that required tuition, credentials, and years of uninterrupted study. He had left school early to support younger siblings, and by the time Gregory was born, wages from the hospital were what kept the family housed. When doctors spoke kindly with him during overnight breaks, he asked thoughtful questions. When they treated him as though his intelligence ended with his broom, he went back to work without making a scene.
"He used to tell me knowledge belongs to anybody willing to learn," Hamilton continued. "But a profession is different. A profession has gates, and most of those gates cost money."
As a teenager, Gregory hated those gates. He hated seeing people walk past his father in the hospital corridor without acknowledging him, and he hated that Martin arrived home exhausted after performing work the hospital could not operate without. He promised himself that one day he would be wealthy enough that nobody could treat him as invisible. Then, over decades of success, he had gradually become a man who made other people invisible himself.
Hamilton turned the truth over silently before he said it. "My father died at fifty-three. He never got the chance to study the way he wanted, and I spent the rest of my life pretending I was nothing like him. Tonight I looked at you and did what the people who hurt him used to do."
Miles sat very still. He was accustomed to adults discussing him in the third person, as if he were a problem waiting to be transferred to another department. Hamilton was speaking directly to him now, without jokes or excuses. The man seemed embarrassed, and Miles did not know what a child was supposed to do with the embarrassment of somebody who had so much power.
